My invention relates' 'to' load binding devices? and' pa'rticulai'ly tothe binding together of the parts or. a load to checkpossible shiftingduring transportation by rail; road, or water.

larly when covering rough ground, and in-turn To prevent such shifting aplate [6 (Figure- III), whioh may be-of triangular or of 5 otheroutline-"is held by an elongated flexible element such-asa chain [8against the forward end of thloadytheplate beingheld against the threehogsheads in the firsttier; and the chain passing rearward below-theupper row of hogsheads, and between the two lower rows, which areusuallya few inches apart. Preferably :the :chainis swiveled to the. frontplate,-and its connection may 'b'eof any suitable character, such as byan eye-bolt zflporby passing the": end of the chain through an orificein the center of theplate, and. securing it at the front. "'At the rearof the load the chain-is tightened and secured to arear plate- 22. inabutment with the rearmost-tierqofhogsheads. V

' The rear plate 22, which carries "the tightening means; is placedagainst the rear end of the load, and in 'contactwith the rearinost'tieroi the upperand thetwo lower rows "or hogsheadsj; The plate 22 and theplate 16 each have a hook or up 24' at their upper margin, designed torest upon the inside of the rim of the contacted hogshead or barrelinthe upperrow; and to prevent thelslipping of this lip from the said Iweld v to, or passthrough this lip a spike 25, or a similar projection,designed to securely engage the said rim. See Figures IV and. V. I p

If the plates I6 and 22 are madetriangularin shapa their upper. cornerswill-lie against the. lower-.partrofthe rims of the foremost and therearmostthogshead in theupper row; as in Fig ure II at .3 and the lowercorners of the plates will lie against the upper part 0f.the rims'of.the foremost and rearmost'hogshea'ds 'in the two lower rowspasat5'and 1. The binding. chain: I8 is secured to; the 'front platePlfilata point substantially at itsvcenter- (Fig. III); and :the other end ofthesaid chain passes through an opening ororifice 9. approximately atthe center of the rear plate 22 '(Figs. IVJVI and VII). The load isbound by tight-t. ening the chain at the-plate 22;:the tightening ofthe-chain drawing-the plates l6 and 22 toward one another.

Onthe face'of plate 22, and below the orifice 9, ther-e are-secured twobrackets, 26; 26; which brackets support a shaft 28; and on this'shaft'is rotatably' mounted a chain pulley 30; A part of this chainpulley iscut-away (Figs, VI; VII, and XI) asit doesnot cooperate with the chain,

a and in "order that a seat may be furnished-for 3 the chain holdingnotched plate 32; to which seat this plate may be welded or bolted.

At 34 is a forked lever. The arms 36 of this forked lever are secured,by welding or other suitable means, to either side of the pulley 30; sothat by pulling down on the lever the pulley may be rotated on the shaft28. The arms 36 also are secured to the plate 32 so thatthe lever alsopulls down on this plate, in which is the notch 38 for engaging andholding a link of the chain (Figs. IV, VI and VII), but through whichthe chain cannot pass.

The pulley 30 essentially is a part of the lever 34, and couldbeintegral therewith, as it merely forms acurved bearing surface for thechain passing to the notch 38 in the plate 32.

In Figure VI the lever is shown turned upward, almost to the limit ofits throw; and the chain I8 passes over the pulley 30, and is caught at46 in the notch 38 of plate 32. If a downward pull'be now, exerted onthe lever 34,'the chain I8 will be pulled through the orifice9 in plate22, as seen in Figure VII. In order to tighten the chain still more, thelink at 46 must be freed from the notch 38 in plate 32, and-a hold thentaken on the chain several links higher up. Before-this can be done: thechain must be secured; and this isdone at the orifice 9 in the plate 22.

In Figure VI thechain I8 is nate links lying in a horizontal plane andwith the intervening links disposed in a vertical plane. This positionmay be held to some extent by providing a groove I I (Fig. XI) aroundthe pulley into which the vertical links will fall. But though the linkat 42 may be in a vertical plane, and be so heldby the groove I I inpulley 30; the link at 44 projecting partly through orifice 9 in plate22, may not be quite vertical, because, though link 42 is held vertical,a small amount of twist can be put in the chain from link to link. Forthe same reason: the links on either side of link 44 may lie in a plane,a little inclined from. the horizontal. Furthermore it cannot beforetold before tightening the chain, whether the link at 0rifice9 inplate 22 will be a horizontal link or a vertical link, or a linkslightly inclined from the horizontal plane or from the vertical plane,or in which direction from the vertical plane.

'In Figure VII a horizontal link 46 is shown partly through the orifice9. In Figure VI the vertical link 44 is shown at the orifice 9. Ineither case, the link which is at the plate 22-that is, link 44 or link46-must be held from any backward or chain slackening movement beforethe lever is released to free the link from the notch 38in plate 32.

Refer now to Figure VIII, together with Figures VI and VII. Adapted toslide upon the face of plate 22; between the brackets 26 and inwardly ofthe pulley 30, and extending downward to form a long handle, is thechain holding device 50; which will be referred to hereinafter as thelatchbar. This latch bar 50 is provided in its upper portion with anelongated opening 52 through which the chain- I 8 extends, and is heldin closely spacedrelation to the plate 22 by means of a pair ofoppositely disposed, aligned pins 62 secured to the brackets 26 andlocated below the opening 9, and a bridge bar 54 secured t the plate 22and located above the opening 9. The bridge bar 54 and pins 62 willprevent the latch bar 50 from falling away from the plate 22 but willpermit a limited sidewise movement as indicated in Figures IX and X.Likewise, due to the shown with alter-- passage of the chain I8 throughthe opening 52-, the latch bar will be prevented from dropping in avertical plane except within the limits of the opening 52.

Formed integrally with the upper end wall of the opening 52 is acentrally disposed, downwardly extending pin 56 which divides theopening into narrow side portions 58 and 59 substantially longer thanthe central portion thereof. With this construction, the chain may beengaged by the latch bar to prevent retrograde movement of the chainupon release of the lever 34 therewith, regardless of whether ahorizontal link or a vertical link is disposed within the openings 9 and52. If a horizontal link is so disposed, a lowering of the latch barwill pass the pin 56 therethrough, and if a vertical link is sodisposed, a slight lateral shifting and lowering of the latch bar willcause such link to be received in one of the narrow portions or slots 58or 59, depending on which direction, if any, the link is inclined fromthe true vertical, and, to the direction that the latch bar is shiftinglaterally. In any case, engagement with either a vertical or horizontallink located in the opening 9 will prevent retrograde movement of thechain so the lever 34 may be released, and the chain may be engaged withthe latch bar regardless of whether a horizontal or vertical link islocated at the openings 9 and 52.

Though the latch-bar 50 is held upon the face of the plate 22 by thechain passing through the orifice 9 and then through the opening 52 inlatch-bar 50; still it must be held free of the chain during thetightening operation. This may be done manually; but preferably by some.form of lock or catch, or by roughened or corrugated surfaces. I haveshown a simple means for holding the latch-bar free of the chain inFigures IV, V, VI, and VII, wherein 60 is a flat spring riveted orbolted to the face of plate 22 above the latchbar 50. It might also beriveted to the bridge 54. To hold the latch-bar in its upper position,the bar is pushed upward, so that the end of the bar comes under spring60, and is held by it against plate 22; The plate 22 being six feet ormore from the ground when in place against a load of hogsheads: thelatch-bar 50 and the lever 34 are preferably made of such a length thatthey will be within convenient reach of a man standing on the ground.When it is desired to shift the latch bar laterally so as to positionone of the slots 58 or 59 properly with respect to the chain linklocated in the openings 9 and 52, the bar may be moved about the holdingspring 60 as a. pivot. V

' In .this specification, and in the claims, I have used the word.chainto designat the means by which when tightened the load may be boundtogether. Part of this tightening means may be Wire rope. and only theafter part, at plate 22, chain. This would reduce the weight. In FigureIII the chain I8 is shown attached to the plate I6 by an eyebolt 20.Usually an eyebolt is held tightly to its seat by a nut drawn up tightlyon the shank of .the bolt on the other side. this case I prefer not todraw the nut up tight, but to leave it partly drawn up; then fixing'iton the shank by spot welding or other means, so that the eyebolt shank,between the eye and the nut, is free to turn in the plate I6. This makesa swivel connection which is an advantage when coiling or handling thechain or wire rope which is attached to the eyebolt and to the plate I6.

a normally vertical bar transversely displaceable from the vertical toan acute angle on either side of the vertical, said bar having slots onopposite sides of its longitudinal center for selective engagement witha link of the chain disposed at an acute angle to the vertical, saidspaced slots forming a pin disposed between the slots atthe longitudinalcenter of the bar for insertion through a substantially horizontal linkof the chain.
